Specification of Letters Patent.

Patented May 1, 1906.

Application filed August 31.1904. Serial No. 222,886.

To all whom it may concern,.-

Be it known that I, BERNT ANDREAS NOR- MAN, a citizen of the UnitedStates, residing at Logan, in the county of Cache and State of Utah,have invented a new and useful Cold- Storage Building, of which thefollowing is a specification.

This invention relates generally to coldstorage buildings, andparticularly to that class in which are employed an ice-chamber, astorage-chamber, and a system of cold and warm air lues or ducts.

The object of the invention is in a ready and practical manner to causethe cold air passing from the ice-chamber to be split or deflected,thereby to secure equal treatment pf all the matter contained within thechamer. A

With the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of a cold-storage building, aswill be hereinafter fully described and claimed.

In the accompanying drawing, forming a part of this specification, andin which like characters of reference indicate corresponding parts, thefigure is a view in vertical section through a cold-storage chamberconstructed in accordance with the present invention.

Referring-to the drawing, 1 designates the outer wall of the. building,and 2 the inner wall. Each of these walls consists of two thicknesses ofboards or planking interposed by insulating or building paper 3, whichoperates in a manner that will be well understood to lag these walls.The ceiling 4 constitutes a continuation ofthe inner wall 2 and isconstructed in a similar manner. Arranged between the inner and outerwalls is a division-wall 5, which extends from the floor of thestructure to the eaves of the roof and consists of spaced planksinterposed by suitable insulating material 6, such as damp sawdust,sand, or the like. The roof 7 constitutes a continuation of thedivision-wall and is constructed similar thereto-that is to say, it iscomposed of spaced planking interposed byinsulating material 8. Thespaces between the division-wall and the inner and outer walls 1 and 3constitute air-spaces 9, which still further operate to effectinsulating ofthe structure, similar spaces 10 between the roof and theceiling serving to insulate this portion ofthe structure. The floorofthe building consists of double thicknesses of planking 11 and 12,interposed by insulating or building aper`13, the plankings being spacedby insu ating material 14, forming a continuation of insulating material6 in the divisionwall and insulating material 8 in the roof, and by thisarrangement it will be seen that the storage-chamber 15 is entirelyinclosed by an insulated sheath or shell. It is to be understood thatthe end walls are constructed the same as the side walls, and as thiswill be readily understood detailed illustration thereof is deemedunnecessary.

Arranged near the roof ofthe structure are joists 15, upon which issupported an icechamber 16, the sides of which are imperiorate and thebottom of which is formed by oppositely-inclined drip-boards 17, whichrest upon the j oists. The space 18 between the opposed ends of thedrip-boards constitutes a cold-air escape, beneath which is arranged adrip-box 19, secured to the under side of the joists and extending theentire length of the structure, as does also the icechamber.

Extending lengthwise oi the structure and spaced from the inner walls 3and ceiling 4 is a supplemental wall 20, which extends from a point nearthe floor to a point near the apex of the ceiling, the opposed ends ofthe wall being spaced apart within the ice-chamber at 21 to permitpassage of the warm return air to the ice-chamber, where it is againcooled and passes to the storage-chamber. The flues or passages 22,formed between the inner wall 3 and the supplemental wall 20, are ofsuch size as to permit free and uninterrupted circulation of the airfrom the bottom of the storage-chamber to the ice-chamber, and so on.

In the operation of the structure the air that has passed through thematerial within the storage-chamber enters the intake-mouths 23 of theflues 22, passes up and into the icechamber near its apex, thence downthrough the ice, and upon contacting with the drippan is split, partpassing around one side the pan and part around the other side, so thatproper treatment of all the material within the chamber will be eiected.f

By making the sides of the ice-chamber imperforate the air will becaused to circulate through the entire body of ice before escapingthrough the space 18 between the 1ro TOO drip-boards, thereby effectingrapid and positive cooling of the contained air Within thestorage-chamber. y

The structure of the present invention, while exceedingly simple, willbe found of the highest eciency and durability in use, and by reason ofthe manner in which the air is caused to impinge the ice the maximumrerigeration will be secured with the minimum expenditure of ice.

Having thus described the invention, what is claimed is- A cold-storagebuilding consisting of outer and inner lagged walls and an intermediatelagged divisi on-wall formingair-spaces at opposite sides thereof, alagged roof and flooring constituting continuations of the division-wallsaid roof being peaked, an inner lagged wall constituting a portion ofthe roof zo and forming an air-space thereabove; supplemental wallsWithin lthe building and spaced from the inner lagged walls of the sidesand roof `and terminating above the iioor and adjacent the apex of theceiling, said supplemental walls forming flues Jfor conducting air fromthe floor oi the building to the apex of the ceiling, an ice-chambersupported from the ceiling and having imperiorate walls and an outlet inthe bottom thereof; and a drip-box disposed below the outlet, theair-outlet between the upper ends of the supplemental Walls beingdisposed above the center of the ice-receptacle.

In testimony that I claim the foregoing as my own I have hereto a'llixedmy signature in 3 5 the presence of two Witnesses.
